Timo, Thank you. I am exploring my options. Are all three steps (Assemble, Solve, Update) normally parallelized? I also noticed that AMG does itself use UMFPack as a coarse solver, it it (well, SuiteSparse) is installed in the system. It does so even in parallel mode, so maybe UMFPack can

Hi Timo, After some time on DuMux 3.1 and AMGBackend, I have moved to DuMux 3.2 (and thus AMGBiCGSTABBackend, since the AMGBackend is deprecated). I would like to give a try now to ILU0BiCGSTAB and/or UMFPack solvers, if it is possible to run them in parallel. Is the information that you
